The toolset text for skillModifierAttribute in the trait editor lists four attributes (str, cha, int, dex) for traits -- does this mean Wisdom (wis) can't be used to modify traits as skills, or is it just not listed? Thanks!

Just checked it out in the code base: gcPassSkillCheck.cs (and therewithskillModifierAttribute) does take wisdom into account, too .So the documentation is wrong, I will change the docu in toolset next beta patch.
